UNITED sTATEs PATENT oEEro MICHAEL FRANK BROGAN, OF LAWRENCE,MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON,NEW JERSEY, A CORPORATION OF NEW JERSEY.

CEMENTING-MACHINE.

To all whom it may concern:

Be it known that I, MICHAEL FRANK' BROGAN, a citizen of the UnitedStates, residing at Lawrence, in the county of Essex and Commonwealth ofMassachusetts, have invented certain Improvements in Cementing-Machines,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindieating like parts in the several figures.

This invention relates to means for coating stock and is herein shown asembodied in a machine for applying cement to shoes.

It is customary to apply cement to the bottoms of Goodyear' shoespreparatory to laying the outer sole, the cement being employed for thep urpose of holding the outer sole temporarily on the shoe and forforming a tight joint between the outer sole and the welt, inseam andlling after the outer sole has been permanently attached. Ce-

-ment is also applied tothe channel and channel flap of the outer soleafter the outer sole has been stitched to the welt, the iiap then beinglaid to cover the line of stitches. In the first case a comparativelywide cement applying means or distributer is advantageous, in the seconda narrower one.

The present invention is shown as embodied in a device which is capableof accommodating distributers of either type, as desired, the featuresof said invention being applicable to distributers of any width.

It is usual to allow the cement to fall upon the dist-ributer at somegiven point in its width and to employ spreaders to work the cementacross the face of the distributer and spread it in a layer of asuniform thickness as possible. I-Iitherto these spreaders have been ofthe type known as doctors or Scrapers which operate upon a comparativelysmall area at any given moment and whose principal extent is in adirectionv approximately transverse to the path of movement of saiddistributer; and although various types and combinations of types ofthese spreaders have been used the result has jnot been altogethersatisfactory where wide distributers were used.

One feature of this invention relates to a spreader of a new type whichoperates on a considerable area continually so as to reach .all parts ofsaid area simultaneously and which extends for some distance in proxim-Specicaton of Letters Patent.

ity to the working face of the distributer and conforms approximately tothe outline of said working face. Preferably this spreader is adjustableto regulate the thickness of the layer of cement; and if the outline ofthe working face of the distributer makes it desirable, said spreadermay be flexible. In the latter case it may simplify the adjustability tomake the spreader resilient. This latter quality is also desirable wherethe distributer has an unyielding working face, since in that case, itwill allow the passage of any particles of foreign matter which maybecome lodged on the face of the distributer and which otherwise mightcause parts of the device to bind or break. This spreader may be a flatresilient member of approximately the width of the distributer, xed atone end and having an adjustable linger bearing upon a point near thefree end and serving to move t-he latter end of the .spreader toward thedistributer to spread the cement in an even layer. It is to be notedthat the spreader accomplishes the further purpose of controlling theamount of cement carried away by the distributer', since the only pathof escape for the cement is by way of the adjustable end of thespreader. Moreover, where the distributer takes the form of a brush thespreader may, if desired, be forced down upon the brush and thus, bycompressing the brush, limit the amount of cement which it will take up.

In applying cement to stock, particularly in applying cement to thebottoms of filled shoes it is found that particles of foreign matter arepicked up by the distributer and that these particles tend to interferewith the flow of cement to the distributer.

Another feature of my invention, therefore, relates to the provision ofcement delivery means provided with means for preventing such particlesfrom clogging the flow of cement; and this means may conveniently takethe form of a protector or deflector extending at an angle to thedirection of flow of the cement and approximately in the direction ofmotion of the distributer at the point of delivery.

In practical use of the device it sometimes happens that cement worksdown upon the side face of the distributer and from this point to theside of the stock. This results in a daub or stain of cement on thestock at a point where it may be injurious to the value of the stock;and to prevent the injurious results referred to above, another featureof this invention relates to means whereby one side face of thedistributer is kept free from cement. This means may be of any suitableform and in the illustrated embodiment is shown as a fiat4 wiper havinga =beveled front presented toward the oncoming portion of thedistributer, the arrangement being such that the yielding part of thedistributer is crowded to one side as it passes the wiper, and anycement which may have worked down on this side is removed.

IV hen the distributer is a brush this wiper serves the further purposeof compacting the bristles laterally from one side and preventing theouter bristles from straggling and daubing the stock at one side of theportion which it is intended to coat with cement.

A further feature of my invention relates to a provision for allowing aflexible distributer to spread when stock is pressed against it; andthis may be conveniently provided for by forming the side plates withbeveled edges which diverge out'- -wardly from the distributer. Withthis construction, when a brush for example, is employed, the bristles,as they reach their operative position and are no longer confined by thesides of th-e hood, are allowed to spread so as to readily give up theirload of cement and work it thoroughly into the stock.

'Ihese and other features of the .invention, including certain detailsof construction and combinations of parts will be explained inconnection with the following description of a machine and will bepointed out more delinitelv in the claims.

Figure 1 is an elevation; Fig. 2 is a transverse section on the line 2-2of Fig. 1; Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2;Fig. 4 is a detail perspective of the cement delivery means and itsassociated protector; and Fig. 5 is a perspective showing` the interiorof the hood, one of the side walls having been removed.

A main casting` 1 is provided with a cement conduit 2 and is adapted tobe fixed to the frame of the cementing machine in such a manner that theconduit leading from the cement reservoir shall be alined with the inletto the conduit 2. Any manner ot' so xing the casting may be employed, asfor example, a screw bolt passing through the bore 8. The main casting 1forms in effect a hood composed of a cover 4 and side walls 5 and 6, thewall 6 being shown as separate and held in adjusted position by screwbolts 7 which are adapted to slide in slots 8 in. the cover.

IVith this construction the width of the hood may be varied toaccommodate distributers of different widths. A bearing 9, which may beof brass or other suitable material, is tixedly mounted in an opening 1Qin the wall 6, and against this bearing is seated a side plate 12. Thecorresponding opening 11 in the opposite wall 5 is adapted to tit snuglyabout a hollow stem 13 which carries the opposite side plate 14.

'Between these plates 12 and 14 the dist-ributer, herein shown as arotary brush, is held. The bristles are mounted in an annular member 15which is commonly of wood; and inserted through the annular member is acylindrical hub 16 having its ends bearing in sockets in the sideplat-es 12 and 14. To compel the rotation of the brush with the sideplate 14 there is provided in the annular member 15 a radial slot whichfits over a pin 17 fast to the plate 14. Packing may be employed, ifdesired, bet-ween the plates 12 and 14 and the walls of the hood.

In order to obtain a coating of'uniform thickness on the distributer, aspreader 18 has been provided which conforms throughoutits extentapproximately to the outline of the working faceof the distributer andis ot a width approximately equal to that of said distributer. In thepresent embodiment the spreader 18 is shown as a resilient strip bentlback upon itself at one end and fastened by a screw 19 to the cover ofthe hood. But although the spreader has been shown as a resilent stripiixed at one end it should be understood that neither the shape, nor theresiliency, nor the manner of fastening is indispensable, since it isevident that a rigid spreader, for example, could be used so long as itwas provided with a face which conformed approximately to the outline ofthe face of the distributer. And although the present spreader has beenshown as extending over almost the entire upper face of the distributer,it should be understood that no particular length is indispensableprovided the spreader covers a considerable area so as to operate uponall points in that area simultaneously. In order to obtain a layer ofcement of desired thickness, means is provided for moving the spreadertoward and from the distributer. In the illustrated embodiment theresiliency of the spreader accomplishes the latter movement while theformer is accomplished by a strip 20 extending through a slot in thecover ofthe hood and having its opposite end bent and formed as a yokewhich fits in an annular groove in a thumb screw 21, whereby, as thescrew is advanced, the spreader 18 is moved toward the d'istributer.Instead of the means described above the spreader might be differentlymounted-in short any suitable means for moving the spreader toward andfrom the distributer may be employed.

In addition to its function as a spreader the member 18, in anyembodiment of the invention wherein the distributer is of a yieldingnature, operates also as a regulator to regulate the amount of cementtaken up by the distributer' and thus indirectly, the flow of cementfrom the cement delivery means. This is particularly true where thedistributer takes the formof a brush, a brush being in somecharacteristics similar to a sponge, the spaces between the bristlescorresponding roughly to the pores of the sponge. In this case it ispossible to compress the brush to such an extent that its capability fortaking up cement is greatly reduced.

In applying cement to stock, and particularly in applying cement to thebottoms of filled shoes, it is found that particles of foreign matterforexample, cork-are picked up by the distributer (hereinafter referred toas a brush). Means to remove the particles is provided, said means beingshown as a bent member 22 having a slot 23 at one end through whichpasses the screw 19, and having at its other end a series of teethforming a comb which rests upon the face of the brush, the screw andslot connection furnishing means for adjusting the comb. Notwithstandingthis provision for removing particles of foreign matter, a portion ofthese particles fails to be removed and, being carried forward by thebrush, is liable to accumulate in and about the mouth of the cementsupply conduit and to clog or even entirely shut ofi:1 the flow ofcement. 'I'o prevent such clogging, a cement delivery means has beenprovided which is so protected that particles of foreign matter areprevented from working into the conduit. In the illustrated form thedelivery means includes a slot 2-1 in the spreader 18, and the protectoror deflector is shown as a tongue 25 having a reduced end which passesupwardly through the slot and is riveted at 26 to the spreader, thespreader having a comparatively abrupt bend on each side of said slot soas to preserve the general semi-circular outline of said spreader. Itshould be understood, however, that this construction is purelyillustrative. The cement delivery means, although shown as including aslot, might be a tube or nozzle of suitable form and the protector mightbe dierently mounted, the principal requirement being that cementissuing fromithe delivery means shalll be deflected in the direction ofmovement of the brush at the point of delivery or that the cement shallbe delivered first to the protector and then to the brush. With regardto this member 25 it should be noted that it may serve the furtherpurpose of retracting the bristles, as they pass beneath the cementdelivery means, in such a manner that the cement is delivered among thebristles and the brush is properly loaded with cement. It should also beunderstood that its function as a bristle retractor is quite distinctfrom its function as a protector of the cement delivery means and thatconsequently, the retractor might take a different form if desired. Themember 25 also serves the further purpose of preventing the cement fromflowing down over the rear portion of the brush and dripping upon thework.

As has been stated it sometimes happens that cement from the side faceof the brush works down on to the side of the stock. In order to guardagainst such an occurrence a cleaning means is provided which operatesto keep one side of the brush free from cement; and in the illustratedform this means is shown as a flat scraper or wiper 30 held by a screw29 to the side wall of the hood and having a beveled front 28 whichopposes the oncoming portion of the brush, the construction being suchthat as the bristles at the side of the brush ride up the bevel 28 andpass along the plate 80 any cement clinging to them is removed. In theillustrated form the spreader 18 is cut away at the side to allow it tobe adjusted without permitting escape of cement.

It is desirable to allow that part of the brush which is contacting withthe stock to spread in order that the cement may be worked thoroughlyinto the stock and that the brush may give up as much of its load ofcement as possible. To provide for this, plates 12 and 14 are formedwith bevels 31. The portions of the brush within the hood are supportedby the sides of the hood, but as soon as these portions pass out intooperative position the beveled edges of the plates allow them to spread.

At 32 is shown a socket for the reception of a support vfor a channelflap guide when the device is used for applying cement to the channelflap.

In operation a rotary shaft mounted on the frame of the machine extendsinto the hollow stem 13 and is adapted to be clutched thereto at will.The clutch having been thrown in, cement is allowed to flow from thereservoir (also mounted on the frame of the machine) into the conduit 2.From the conduit 2 it passes into the cavity 27 and then through thecement delivery means 21 where it is deflected by the member 25 in thedirection of movement of the brush at that point. The screw 21 is turnedto move the member 18 so as to obtain a coating of the desiredthickness, and in doing this the member 18 may be forced against thebrush so as to compress the tufts of bristles and thereby regulate theamount of cement which the brush is capable of taking up. A propercoating of cement having been secured, the stock is pressed upwardagainst the lower portion of the brush thereby causing the brush tospread and the cement to be properly applied. 'As the brush continues inits path, particles of foreign matter which are picked up are to a greatextent removed by the comb 22, while those which pass the comb areprevented by the protector 25 from clogging the flow of cement.

Vhile for convenience the invention has been described as embodied in amachine for applying cement and the coating material has been referredto as cement in the specification and claims, it should be understoodthat the invention is not limited to the application of'cement but maybe used with any liquid or viscous material.

The invention has been set forth in connection with a specific machine,but it should be understood that the machine set forth is 4 onlyillustrative, that various changes other than those already suggestedmay be made and that nothing herein contained is to be construed aslimiting this invention and the scope of its application to the specificmachine shown and described.
